What essential feature must a compressor have for a supplied air respirator?

A supplied air respirator relies on a compressor to provide clean, breathable air to the user. One of the essential features that a compressor must have is a device to prevent over-pressurization. This is crucial because if the air systems become over-pressurized, it can lead to equipment failure and potential safety hazards for the user.

The compressor needs to maintain a safe and consistent airflow without exceeding the designated pressure levels, ensuring that the respirator operates effectively and safely. This feature safeguards the integrity of the system and protects the user from risks associated with high-pressure air supply, thus it plays a pivotal role in the functionality of supplied air respirators.

While filters for odors and chemicals and noise reduction systems can be important features in certain contexts, the prevention of over-pressurization directly relates to the safe operation of the air supply system, making it a fundamental requirement for any compressor used with a supplied air respirator.
